Please suggest somewhere else I should post this. I took an OTA update last night for Lineage4microG and my OnePlus8T just bootlooped. I tried downloading and manually side loading both the most recent and previous versions, but they keep failing with a kInstallDeviceOpenError. I am desperate to get back into my device without wiping the data.
If your phone has a password on it then its data is going to be encrypted until you unlock the phone.
You can temporarily boot a twrp recovery image. It will let you put in your password and decrypt your storage.
You should be able to transfer the files to your PC with a cable then
I couldn’t get twrp to boot :( Any twrp images for my phone are a few years old
Can you get it to boot into twrp via fastboot? If not then you could try flashing stock firmware to see if that resolves the issue. Another thing is you may run into issues installing lineage via twrp. The recommended way is by using their recovery image.
I could not get twrp to boot from fastboot. I’ll look into flashing the stock firmware. Is there a chance that would break anything? I’m somewhat hopeful that an updated LOs4microG is released soon since the one I installed has now been marked as broken.
It shouldn’t, but modern phones are black magic to me, so I may be wrong.
